Mechanism for acid catalyzed enolization.
00:13
So that is going to be, we have a carbonil group and acid hydrolysis is being done.
00:20
So this is going to form a double bond over here.
00:27
If we see the mechanism in this case, so here we have a ch3 group.
00:31
So cs3 can be written as in the expanded form, hydrogen can be written like this.
00:35
And what is going to happen is we have h3o plus.
00:38
So o, h, h, h, h, h, lone pair, a positive charge.
00:46
So what is going to happen is lone pair of electrons on the oxygen atom is going to take up this proton, that is h from here, and this is going to form o, h positive charge, lone pair of electrons, hydrogen, hydrogen, and hydrogen.
01:05
Then this can undergo resonance.
01:09
We can have o, h as this one shifts over here.
01:16
Then there will be generation of a positive charge over here.
01:19
And here we can have three hydrogens in this fashion.
01:23
So this one can now shift over here as we have oh in the system, oh actually h2o, because when h was lost.
01:33
So from this, this loan pair can take up this proton.
01:35
So the final product which we are going to obtain is going to somewhat look like this.
01:45
That is oh, two loan pairs on oxygen, double bond, and here we will have hydrogen and hydrogen.
01:56
So this is the enol form of this...
